|---|---|---|---|---|---|
| Plant Process | pulls water (hydrosphere) and nutrients from the soil (lithosphere) and release oxygen and water vapor into the air (atmosphere)
🗑

||||
| Human Process | built glen canyon using rock material (lithosphere) to control a lake (hydrosphere) as the water evaporates, it moves into the air (atmosphere)
🗑

| Heat | Solar Energy and Radioactivity; influences the Earth more than any other process in the universe
🗑
|
||||
| Solar Energy | (the sun) the Earth is on an axis , and the sun hits the surface at varying angles causing the major climates of the planet
🗑
|
||||
| Radioactivity | (earth's core) responsible for the plate tectonics, most volcanoes, and earthquakes, which are located near plate boundaries
🗑
|

| Weathering | the process of changing structures through the effects of the wind, water, ice, sun, and gravity
🗑
|
||||
| Erosion | the process of moving the weathered materials (rivers, wind)
🗑

||||
| Rock cycle | all rocks come from the mantle (except limestone)
🗑
|
||||
| Igneous | Forms when magma cools (granite, pumice)
🗑
|
||||
| Sedimentary | Forms when layers of sediments are compressed (sandstones, limestone, coal, shale)
🗑
|
||||
| Metamorphic | Forms through the transformation of igneous and sedimentary rocks through heat and pressure (marble, slate, quartzite)
🗑

🗑

| Paleozic era | 570-286 million years ago- Trillobites, shells, mollusks, brachiopods, echinoderms, rise of first vertebrates, rise of land plants, rise of amphibians, insects, seed plants, and trees, and reptiles
🗑
|
||||
| Mesozoic era | 245-144 million years ago: the rise of mammals and dinosaurs, the rise of birds, the extinction of dinosaurs, and the rise of flowering plants
🗑
